    [1] Any time you're working with a flammable substance it is extremely important to make sure you don't put yourself, other people, your property, and the natural world at risk of getting burned or set on fire. Plan to make the firecrackers outdoors so that you don't put your house at risk, and make sure children and pets are kept away from the area.
    • Set up a workspace well away from the house, work shed, and other structures on your property.
    • Don't work on firecrackers near trees, telephone poles, and other outdoor features.
    • It's best to set up on a concrete patio or bare dirt. Avoid working with explosives near dry grass or other plants that could catch fire.
    • Wear goggles to protect your eyes while working with firecracker materials. [2]
  2. Watermark wikiHow to Make a Firecracker
    Firecrackers are made with a shell to contain the explosive materials and a small fuse that you light to set it off. The following materials can be purchased from large department stores that sell ammunition and sporting goods.
    • One ping pong ball for each firecracker you plan to make. [3]
    • Thick string, which will be used as the fuse. [4]
    • A sharp nail and a razor to make holes in the ping pong ball.
    • Duct tape or another sturdy tape to patch up the hole.
    • Black powder, also known as gunpowder, which is available where ammunition is sold. It comes in small canisters. Before buying black powder, get familiar with measures you must take to handle and store black powder safely . [5]
    • Nail polish, which causes the firecracker to make a louder noise.

    Use the nail to make a small hole in the top of the ping pong ball. If necessary, you can use a hammer to help the nail puncture the ball. [6]
  2. Watermark wikiHow to Make a Firecracker
    Use the razor to cut a slightly larger hole opposite the hole you made with the nail. It should be large enough to allow you to pour the powder into the ping pong ball.
    • Use a razor with a handle for greater precision. Be careful not to cut yourself as you wield it; the surface of the ping pong ball may be slippery.
    • If you don't have a razor, use a nail or another item to bore a few holes close together to create a hole large enough to pour the powder through.
  3. Watermark wikiHow to Make a Firecracker
    [7] Cut a length of the string several inches long and thread it through the nail hole in the ping pong ball. Pull it through so that the base of the string hangs in the center of the ball, and the end of the string juts out from the ball by an inch or two.
    • If you have trouble threading the string through the hole, dip it in a bit of melted wax to create a hardened tip, then push the tip through the hole.
    • For a slower-burning fuse, dip the length of the string in candle wax or beeswax. When you light the fuse, it will burn more slowly before the firecracker explodes.
  4. Watermark wikiHow to Make a Firecracker
    [8] Use a small spoon or funnel to fill the ball 3/4 full of the black powder. Don't overfill the ball.
    • Never smoke or light a flame while handling black powder.
    • Take care not to spill any black powder in your workspace. If you spill some, clean it up with a dustpan and broom and dispose of it safely.
    • As soon as you're finished with the gunpowder, close the canister tightly and store it in a cool, dry place away from flammable or combustible substances.
  5. Watermark wikiHow to Make a Firecracker
    [9] Use a piece of duct tape to patch the hole, pressing down firmly to make sure it doesn't come loose. The fuse hole should not be covered.

    Use nail polish to paint the outside of the firecracker. Allow it to dry completely.

  1. Watermark wikiHow to Make a Firecracker
    An open concrete lot away from buildings and cars is the ideal place to use a firecracker. Do not set off a firecracker near people, houses, or any other structures that might catch fire. [10]
  2. Watermark wikiHow to Make a Firecracker
    Use a match or a lighter to carefully light the tip of the fuse. Don't light the fuse at its base, or the firecracker may explode prematurely.
  3. Watermark wikiHow to Make a Firecracker
    Don't linger close to the firecracker after it has been lit. Set it on a cool, dry foundation - not grass or another flammable material - and quickly walk several yards away.
    • DO NOT light the fuse until children, pets, and other people are at a safe distance from the firecracker.
    • Never place a firecracker inside a glass bottle or drinking glass. The glass may break, and the aftereffects could be very dangerous. [11]

    What color will the explosion of a firecracker be?
    Community Answer
    It will be a white flash, as there is no metal to burn, which is what gives off the colors.

      Tips

      • The string idea for a fuse rarely, if ever, works. You don't need rocket science to know that a string will stop burning once it hits the tape. You can buy model cannon fuses from hobby stores.

      Tips from our Readers

      The advice in this section is based on the lived experiences of wikiHow readers like you. If you have a helpful tip you’d like to share on wikiHow, please submit it in the field below.
      • Sweep up any spilled gunpowder gently. Static sparks can ignite it. You also want to make sure the area where you plan to ignite your firecracker is free of debris that the explosion might fling into your face.
      • Save your firecracker for a special occasion rather than just setting it off on a random day. Occasions that feature firecracker celebrations include New Year's Eve, Chinese New Year, and Diwali (Deepavali).
      • Be careful after you've ignited your firecracker. Don't panic and throw it randomly—you could hurt someone or damage property.

      About This Article

      Article Summary X

      To make a firecracker, you’ll need a ping pong ball, thick string, a sharp nail, a razor, duct tape, and gunpowder. Once you’re ready to start, set up a workspace in an open area, like your back yard, just in case anything goes wrong. Start by making a small hole in the top of the ping pong ball with the nail. Then, use the razor to slice a slightly bigger hole at the opposite end of the ball. After you’ve made the 2 holes, cut a length of string a few inches long and thread it into the small hole of the ping pong ball. Next, pour gunpowder into the big hole until the ball is full. When it’s full of powder, patch the hole with duct tape to seal the ball. When you're ready to light your firecracker, make sure you're in an open space away from people, cars, and buildings. Then, light the tip of the fuse with a lighter or match and set it down on hard ground to avoid starting a fire. Make sure you walk at least 5 yards away after you've lit your firecracker. For more tips, including how to paint your firecracker, read on!
